SELF-CLOSING-VALVE nozzrin Application filed January 19, 1926. Serial No. 82,287.,

This invention relates to self-closing valve nozzles and especially adapted for use on the hose of a gasoline filling pump.

Ill

The nozzles now in use at gasoline filling stations are usually hung on the pump, or

other support, with the open end of the nozzle upward. Dust may be blown and rain may fall into the open end of the nozzle when hung in this manner and any water or dirt in the nozzle goes into the automobile tank with the gasoline. ater or dirt causes engine trouble. Some operators of filling stations require placing a cover over the open end of the nozzle to keep dust and rain out, but the workmen often neglect to place the cover on the nozzle and the cover liable to be mislaid or lost. The objects of my invention are to provide a nozzle which, when hung up with the open end upward, will automatically close to keep out dust and rain, and which will, when turned downward to fill a tank, automatically open to allow full and free passage of the gasoline, and to providea nozzle which is free of protruding parts so that it will readily pass in and out of the tank opening without binding or injuring the tank.

These objects, and other advantageous ends which. will be described hereinafter, I attain in the following manner, reference being bad to the accompanying drawings in which Figure 1 is a central section, partly in elevation, of a nozzle made in accordance with my invention showing it attached to a hose,

Figure 2 a fragmentary section of the nozzle shown in Figure 1 illustrating it in position for filling a tank,

Figure 3 an enlargedsection on line 33 of Figure 1, H

Figure 4 an enlarged section on line of Figure 2, and

Figure 5 a fragmentary view similar to Figure 1 showing a modified form.

Referring to the drawings, 1 indicates the hose of a filling pump, 2 my improved nozzle secured to the pump and having a hook 3 of any suitable construction for hanging it on a pump or other support. The nozzle has a seat 4 around its open end, a threaded part 5 adjacent the seat and a shoulder 6 adjacent the threaded part. A ball 7 rests on the seat when the nozzle is upright as shown in Figure 1. The ball is guided onto the seat by a perforated cage 8 Which'is screwed onto the threaded part 5 with the ball enclosed. The base 9 of the cage abuts shoulder 6. The dimensions of the cage are such that, when attached as shown in Figure 1, it will not extend radially beyond the "circumfereuce of the nozzle. This allows the nozzle to be inserted in or withdrawn from a small opening 10 in a gasoline tank 11 without danger of protruding parts striking and injuring the tank.

The side wall of the cage 18 perforated to allow full passage of gasoline from the nozzle. The perforations are preferably in the form of slots 12 so thatspaced guiding members 13 are left for guiding the ball onto seat 4. The outer end of the cage has an aperture 141: for receiving the ball and keeping it in position when the nozzle is inverted for filling a tank as shown in Figure 2.

In Figure 5, I have shown a form of nozzle which may be attached to the regular nozzle now in'use. It consists of a sleeve 15 having a seat 1 similar to the seat- 4 shown in Figure 1, a threaded part 5 and a shoulder 6 The other parts co-acting with seat 41, threaded part 5 and shoulder 6 are similar to the ones shown in Figure 1, and I have therefore given corresponding parts similar reference characters with the expo nent a. Sleeve 15 may be secured in the regular nozzle 16 in any suitable manner preferably by a set screw 17.

hen filling a tank, the nozzle is inverted and passed through opening 10 into the tank as shown in Figure 2. Ball 7, being free to fall, will be guided by members 13 into aperture 14 in the outer end of cage 8. Gasoline passing through the nozzle will pass over the ball and will exert a practically equal force on all sides of the ball, which keeps the ball in aperture 14, thus preventing sidewise and spinning movement of the ball against cage 8. After the tank is filled, the nozzle may be easily withdrawn from the tank through opening 10 without danger of protruding parts striking and injuring the tank. The nozzle is then hung on the pump or other support with its open end upward. Ball 7, then being free to fall, will be guided by members 13 onto seat 4, thus automatically closing the nozzle.

The nozzle thus automatically opens when invertedfor filling a tank, and automatically closes when hung in upright position.

hile I have described my invention as aball adapted to rest on the seat, and a perforated cage securedito the nozzle andenclosing the ball to guide the same onto the seat, the outer surface of the cage being substantially flush with the periphery of the nozzle.

2. A nozzle and a cage secured thereto, the outer surface of said cage being flush with the periphery of the nozzle, means in the cage for closing the nozzle when it is held in one position and for allowingliquid to flow therefrom when it is held in a different position, and a plurality of seats for holding said means stationary in said different positions.

3. A nozzle having a seat at its open end, a threaded part adjacent the seat and a shoulder adjacent the threaded part; a ball adapted to rest on the seat, and a perforated cage, for guiding the ball onto the seat, screwed onto the threaded part and abutting:

the shoulder, the perforations in the sides of the cage being adapted to allow passage of liquidirom the nozzle and the perforation in the outer end of the cage being adapted to receive the ball and keep it in position during passage of the liquid, the outer surface of said cageibeing substantially flush with the periphery of the nozzle.

name to this specification.
